Study and Loan Material for Elementary Schools.—To the 
extent of its facilities, the Botanic Garden will provide, on request, 
various plants and materials for nature study. As far as pos- 
sible this material will continue to be supplied gratis to elementary 
schools in case one or more of their teachers are members of reg- 
ular Botanic Garden classes. Requests from Elementary Schools 
should be made to Miss Elsie T. Hammond, and material should 
be called for at the Information Booth on the ground floor. 
Study and Loan Material for High Schools, Junior High 
Schools, and Colleges 
Available at the Brooklyn Botanic Garden, 1938-1939 
The Botanic Garden is able to supply various plants and plant 
parts for study; certain protozoa; sterilized nutrient agar; and also 
material and mounts for exhibit purposes. When containers are 
necessary, as in the case of agar, algae, and protozoa, they must 
be furnished by the school. 
In the past, the Garden has offered this service gratis, but both 
on account of the increasing demand and because of the decrease 
in appropriations, it has become necessary to make a small charge 
for the material supplied or loaned. A Price List of the various 
materials furnished will be mailed on request. 
Requests should be made by mail or telephone (PRospect 
9-6173), at least one day in advance, to Dr. Elizabeth Marcy, and 
the material should be called for at Room 204. All exhibit ma- 
terial, and other items starred (*) will be mailed if the school pays 
postage.
